This product was evaluated for sunscreen efficacy at CCFT Laboratories Pvt. Ltd. on sample HO/02/BMSUN/09/10/ME under CTRI/2026/02/104308, in accordance with IS 17494:2025 (ISO 24444:2019, MOD) and the COLIPA in-vitro guideline.
1. Study Overview & Design
| Study Parameter | Detail |
|---|---|
| Study Title | Sunscreen Efficacy Certificate for Baby Rich Moisturizing Ultra Light Sunscreen |
| Specific Parameters Measured | Sun Protection Factor (SPF) - In-vivo; PA Rating, Critical Wavelength, Boots Star Rating and Broad Spectrum Classification - In-vitro |
| Why These Parameters Matter | Baby skin has a thinner stratum corneum and less melanin than adult skin, so it burns faster and sun damage accumulates earlier. UVB (290-320 nm) causes sunburn; UVA (320-400 nm) penetrates deeper. A baby sunscreen needs verified protection across both, which is what in-vivo SPF plus in-vitro UVA metrics establish. |
| Study Type | In-vivo SPF evaluation on human volunteers, plus in-vitro spectral evaluation |
| Testing Methods | IS 17494:2025 (ISO 24444:2019, MOD) - In-vivo SPF; COLIPA Guideline - In-vitro PA, critical wavelength, Boots Star, broad spectrum |
| Specific Product Studied | Baby Rich Moisturizing Ultra Light Sunscreen - sample HO/02/BMSUN/09/10/ME (commercial formulation) |
| CTRI Registration | CTRI/2026/02/104308 - searchable at ctri.nic.in |

3. Test Results and Clinical Interpretation
3.1 Laboratory Results
| Outcome | Result | Method | Clinical Classification |
|---|---|---|---|
| SPF (In-Vivo) | 55.937 | IS 17494:2025 (ISO 24444:2019, MOD) | High protection - supports an SPF 50 label |
| PA Rating (In-Vitro) | +++ | COLIPA Guideline | High UVA protection (UVA-PF 8 to less than 16) |
| Critical Wavelength | 378 nm | COLIPA Guideline | Exceeds the 370 nm threshold - broad spectrum |
| Boots Star Rating | *** | COLIPA / Boots method | 60-80% UVA/UVB absorbance ratio |
| Broad Spectrum | Yes | COLIPA Guideline | Protection verified across UVB (290-320 nm) and UVA (320-400 nm) |
3.2 Clinical Interpretation of Results
| Metric | Interpretation |
|---|---|
| SPF 55.937 (In-Vivo) | Under standardised conditions per IS 17494:2025, the product demonstrated roughly 56 times more protection against UVB-induced erythema than unprotected skin. This supports the SPF 50 label on the pack; the "50+" designation is conventionally reserved for measured values of 60 or above (Diffey, 2001, PMID: 11348430). |
| PA+++ (In-Vitro) | PA+++ corresponds to a UVA Protection Factor of 8 to less than 16 on the Protection Grade of UVA scale used across India, Japan, South Korea and Southeast Asia - high, one tier below the PA++++ maximum (Wang et al., 2011, PMID: 21463374). |
| Critical Wavelength 378 nm | Critical wavelength is the point where 90% of total UV absorbance occurs. Exceeding 370 nm confirms coverage into the UVA-I range (340-400 nm) and supports the broad-spectrum classification (Wang et al., 2011, PMID: 21463374). |
| Boots Star Rating *** | The Boots Star Rating measures the ratio of UVA to UVB protection. Three stars indicates a 60-80% ratio (Diffey, 2011, PMID: 21564299). The certificate summarises this as "effective protection against UVB rays while offering a degree of protection against UVA rays". |
| Broad Spectrum | Broad spectrum classification confirms meaningful protection across both UVB and UVA wavelengths; a critical wavelength of at least 370 nm is required (Wang et al., 2011, PMID: 21463374). |

4. Formulation Architecture & UV Filter System
Baby Rich Moisturizing Ultra Light Sunscreen was tested as the commercial formulation. The protection comes from Zinc Oxide in an ultra-light, moisturising base with Calendula Extract and Aloe Vera.
4.1 UV Filter System
| Formulation System | Key Components | Function & Performance Rationale |
|---|---|---|
| Mineral UV Filter | Zinc Oxide | Broad-spectrum inorganic filter covering UVB through UVA-I; photostable, sits on the skin surface and is the filter paediatric guidance generally prefers for babies (Smijs & Pavel, 2011, PMID: 22046105). |
| Ultra-Light Base | Lightweight emollients and film-formers (per pack INCI) | Keeps the texture non-greasy, absorbs quickly and supports the 120-minute water resistance without a white cast. |
4.2 Skin Care & Sensory Profile
| Attribute | Basis | Rationale |
|---|---|---|
| Calendula Extract | Product page | Soothing botanical that moisturises and calms delicate skin. |
| Aloe Vera | Product page | Hydrating, cooling after-feel. |
| Water-resistant 120 min | Product page (WR 120 min - 94.18%) | Tested separately by the brand; reapply after water regardless. |
| Dermatologically tested & Made Safe certified | Product page | Skin tolerance is assessed in the separate patch test certificate; Made Safe screens the formula against a list of known toxins. |
4.3 Exclusion Profile: What is Not in This Formula
| What is absent | Why it matters |
|---|---|
| No toxins, silicones, parabens or mineral oil | Brand claim on the product page. |
| No white cast | Brand claim; the ultra-light base is designed to disperse zinc oxide invisibly on the skin. |

6. Frequently Asked Questions
Q: What does the in-vivo SPF of 55.937 mean in practical terms?
A: Under IS 17494:2025 (ISO 24444:2019), an in-vivo SPF of 55.937 means the sunscreen provided roughly 55 times more protection against UVB-induced erythema than unprotected skin on the test panel. The pack is labelled SPF 50, which this measured value comfortably supports (Diffey, 2001, PMID: 11348430).
Q: What does PA+++ mean?
A: PA+++ is the third tier of the Protection Grade of UVA system used across India, Japan, South Korea and Southeast Asia, corresponding to a UVA Protection Factor of 8 to less than 16 - high UVA protection. PA++++ (16 or above) is the top tier. On this certificate the PA rating was measured in vitro (Wang et al., 2011, PMID: 21463374).
Q: What does a critical wavelength of 378 nm mean?
A: Critical wavelength is the point where 90% of a sunscreen's total UV absorbance occurs. 378 nm clears the 370 nm international threshold for broad-spectrum classification, confirming coverage into the UVA-I range (Wang et al., 2011, PMID: 21463374).
Q: Why does the certificate say 'a degree of protection' against UVA?
A: That is the certificate's own wording, reflecting the Boots *** rating (60-80% UVA/UVB absorbance ratio) and the PA+++ tier. The product is broad spectrum, but its UVA protection is one tier below the PA++++ maximum - typical of mineral-filter baby sunscreens, which prioritise tolerance over the very highest UVA ratios.
Q: From what age can I use this on my baby?
A: Paediatric guidance recommends shade, clothing and hats for babies under six months, with sunscreen on exposed skin from six months onward. For a younger baby or one with eczema or very reactive skin, ask your paediatrician first (Paller et al., 2011, PMID: 21504412).
Q: How much should I apply, and how often?
A: Enough to leave a visible layer - roughly a 5-rupee-coin amount for a baby's face and neck - 15 minutes before sun exposure. Reapply every 2 hours, and after swimming, sweating or towel-drying. The SPF result reflects the ISO application rate of 2 mg/cm²; a thin layer gives much less protection.
Q: How can I verify this study myself?
A: The study is registered with the Clinical Trials Registry - India under CTRI/2026/02/104308, which you can search at ctri.nic.in independently of the brand. The original certificate is linked on this page.
Q: The pack says PA++++ but the certificate says PA+++ - which applies?
A: This certificate records PA+++ measured in vitro under the COLIPA guideline, which is one tier below the PA++++ printed on the pack. PA++++ requires a UVA Protection Factor of 16 or above; PA+++ is 8 to less than 16. The product is still broad spectrum (critical wavelength 378 nm) with high UVA protection, but the on-pack PA rating should be reconciled with this result or supported by a separate UVA-PF study.
Q: Is it really water-resistant for 120 minutes?
A: The brand reports WR 120 min - 94.18% from separate water-resistance testing. That is not part of this efficacy certificate, so it is shown as a brand claim here. Reapply after swimming or sweating regardless.
